So I built BulkImgConvert (<a href="https://bulkimgconvert.com" rel="noopener noreferrer">https://bulkimgconvert.com</a>), a free tool that does it all directly in the browser.</p> <h2> What it does </h2> <ul> <li> <strong>Compress</strong> images by quality, percentage, target size (in MB), or target resolution</li> <li> <strong>Resize</strong> precisely or by ratio</li> <li> <strong>Crop</strong> free-form or with presets</li> <li> <strong>Convert</strong> between JPG, PNG, WEBP, AVIF, GIF, SVG and PDF (plus HEIC as input)</li> <li>Batch processing, so you can do dozens of files at once</li> </ul> <h2> How it works </h2> <p>Everything runs client-side via the Canvas API. Nothing is ever uploaded to a server, your files never leave your device, and it still works offline once the page is loaded.</p> <p>No account, no watermark, no limits. It's just a tool I wanted for myself and figured others might find useful too.</p> <p>Would love any feedback, especially on formats or workflows I might be missing!</p> showdev webdev javascript productivity
